Proactive PD Survey Helps Prevent Future High-Voltage Asset Failures
The project demonstrates the value of early diagnostics and expert intervention at high-profile, mission-critical locations. By identifying developing issues and environmental risks, EA Technology supported the prevention of failure, enhanced operational resilience, and laid the groundwork for long-term condition monitoring.

MV Cable Forensic Investigation Turns Up Major Systemic Concern
A forensic investigation into a university's failed MV XLPE cable revealed a systemic concern with far-reaching implications for the asset owner.
)
Case Study: LV Monitoring Predicts the Distance to LV Cable Fault Caused by Car Collision
After a car crashed into an LV pillar and exposed live conductors, LV monitoring data predicted the distance to the cable fault, speeding up repair.
)
Case Study: Integration of Low Carbon Technologies for TasNetworks
For TasNetworks, we developed options to connect more low carbon technologies such as solar PV and EVs to the LV network at minimum cost.
)
Partial discharge survey of MV switchgear and transformers at SULB Company, Bahrain
Our first PD survey at SULB, a Bahrain steel producer, used the UltraTEV Plus² and UltraTEV Locator to assess MV switchgear and transformers.
)
Project: LV Network DER Hosting Capacity Assessment – with TasNetworks
For TasNetworks, we assessed LV network hosting capacity for DER to support orchestration, capacity trading and transport decarbonisation.
)
Case Study: LV Management with SA Power Networks
We investigated strategies to help SA Power Networks accommodate growing DER on its LV network while maintaining quality of supply.
